Download locations:

Download cumulative patch from GDAL wiki: https://trac.osgeo.org/gdal/wiki/ECW
(Look for the link to download the attachment zip at the bottom of the page)
Apply the patch (set -p[n] as needed)

$ patch -b -p1 < path/to/libecwj2-3.3.patch

The include folder must preexist in the target folder (e.g. /usr/local/libecwj2-3.3)

$ sudo mkdir -p /usr/local/libecwj2-3.3/include

Build the library and install in specified folder (e.g. /usr/local/libecwj2-3.3)

$ cd /path/to/libecwj2-3.3
$ ./configure --prefix=/usr/local/libecwj2-3.3
$ make
$ sudo make install

 Assuming you've installed libecwj library under /usr/local/libecwj2-3.3, the
 procedure of adding ECW support to GDAL is simple and you only need to provide 
 GDAL configure with path to the ECW SDK installation prefix:

$ cd /path/to/gdal
$ ./configure --with-ecw=/usr/local/libecwj2-3.3 --
$ make
$ sudo make install
